From the project

Conception sous KiCad 9 et caractérisation de deux cartes PCB CMS pour l'amplification audio d'un capteur piézoélectrique : préampli, filtre Baxandall (ST TSV912), Loudness et étages de puissance Classe AB (TS4871) et Classe D (TS4962).

Conception, simulation SPICE, routage PCB en composants montés en surface (CMS) et caractérisation expérimentale d'une chaîne complète de conditionnement et d'amplification audio pour capteur piézoélectrique (guitare acoustique, contrebasse). Le système est alimenté en asymétrique (0V/5V) et réparti sur deux cartes électroniques : une première dédiée à la préamplification et à l'égalisation active (filtre de Baxandall), et une seconde intégrant une correction physiologique (Loudness) ainsi que deux étages de puissance sélectionnables (Classe AB et Classe D) pour piloter un haut-parleur de 8 Ω…
